Git and the Umlaut problem on Mac OS X
Today I discovered a bug for Git on MacÂ OSÂ X. For example, I will commit a file with the name Ã¼berschrift.txt with the German special character Ãœ at the beginning. From the command git status I get following output. Users-iMac: user$ git status On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # "U\314\210berschrift.txt" nothing added to commit

Unicode lookup
Character set up to date to Unicode 12. The tool as a whole is a new version, public in early stages. As I work on it, it will be missing features, occasionally its data, and sometimes give errors. Input currently recognised: String with any characters, e.g. ã‹› â˜º ã‹¡ or â‚¬ or (ãƒŽà² ç›Šà² )ãƒŽå½¡â”»â”â”» or á˜›âÌ¤á•á· or à¼¼ ã¤ â—•_â—• à¼½ã¤ or â™¥ï¸Ž â™¥ï¸ or â—¡Ìˆ.
